TO LL WIIOM IT MAY CONCERNz.

Beit known that I, ALFRED Goonnrcn, of Burnt Prairie, in -thccounty ofWhite, and State of Illinois, have invented a new and improvedStump-Extractor; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to makeand use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-I`igure 1 is n. top view of the machine. Y

1r`inre 2 is a section through-thc line a a', lig. l.

Similar letters of reference indicate corresponding parts.

'lhs improvement consists in placing the cxtractingmachincry uponrunners, and so arranging the said machinery that it shall he easilyoperated, simple in construction, und capable of devclopingmuch poncrfor the purpose intended.

Upon the runners R is placed a pyramidal frame, consisting of thestanehions P and the cross-pieces B and braces M. The frame isseeurelyattached to the runners by mortises, tenons, and pins.

A tongue, lT,'is attached in the ordinary manner. Upon the cross-piecesB are pillow-blocks c, bolted firmly thereon, in-to which a shaft, S,works Just inside the cross-picces are two wheels, and the unoccupiedspace between them serves as a drum, upon which is wound o. rope orehairur, hy which the stump `.to be extracted is connected with themachine, the rope r being-passed around it in the usual manner.

One ofthe said wheels isV provided with strong ratchet-teeth onitsperiphery, and of the same width as the rim of the wheel.Thisserratedor ratchet sha-pe of thesaid teeth is for the purpose ofmore perfectly catching into a link, ,hto be hereinafter 'explained'.The other wheel u is of less diameter than the wheel w, and is alsoprovided with rntchet-teeth on its periphery, for a purpose to beexplained.

Both wheels are firmly keyed on to the shaft S. -A pawl, il., attachedto one of the stanchions, catches into the teeth ofthe small wheel u inthe manner common to pnwls. Ayertical stanchion, s', is belted into thestanchion opposite the pawl. This verticalstanchion serves as a fulcrumfor the lever L, which works in a slot eut in the tcp of thc saidstanchion, and is held loosely there hy a through-bolt, y.

The long arm ol` the lever extends Ato the' rear of the machine, and isso bent as to be easily worked by the attendant, when standing 'on thoground behind the runners. I The shortI arm of the lever is providedwith a strong iron link, if, hanging vertically, and always injuxtaposition with any one of the vratchet-teeth on the lever-wheel 1v.I

ln operati-ng this machine, the rope i' is unwound from the drum, and,hy meansl et' its hook 7c, is secured to this stump and its roots. 'lheattendant raises the lever L, and thc link i slips downward on tho topface of thc nearest tooth, and catches under its vertical face. i Y

This action of the link in catching under the teeth is duc to theendeavor of the link, actuated by the force oi' gravity, to assume aperpendiculaipesition.

The lever is then depressed, and the link turns the lcvernvheel a shortdistance. The pawl 7L catches into the teeth of the ratchet-wheel il,and retains thc strain on the rope and stump, while the lever is againlifted, for the link to catch another tooth on the lcvcrwheel u'. Thisoperation is continued` till the stump is extracted. i v

If the ground in.tho vicinity of the stump is soir. and yielding, theexcellence of this stump-extractor will 'he amply appreciated, for, byplacing two stout pieces of plank crosswise underneath the runners, themost miry ground around stumps will be able to sustain the machine whenexerting its extracting tension.

This machine is constructed ci Wood, as to its runners and generalframe, and securely bolted in the common manner. The lever andratchet-wheels nre of iron, and thc shaft upon which they work, inpractice should bc of wrought iron. i

This machine can he used with advantage'for moving heavy timber-logs,when there is snow on the ground,

and answers the purpose of a sling-cart for suoli uses, as, by backingthe runners over the end of the log, `and securing the same with therope or chain, the end can be raised, and the log drawn along by a team`hitched to the tongue T.

Tile lever-wheel w may be constructed vof wood and castmetal combined.

The advantages claimed for this machine are, first, its cheapness andsimplicity of construction; second,

the ease with which .it con be operated third, thcjmall number of itsparts, which permits the machine to be compactly constructed; fourth,its strengtb as awhole, rendering,r it unlikelyto get ont of repair,'thecombination of which above-named qualities renders it o. durable anddesirable machine for all persons needing the same. f

Having thus described vmy invention, what I claim as new, and desire tosecure by Letters Potent, is-

The construction and arrangement of the py'ramidal frame P upon therunners R, shaft S, ratchet-wheels u u', of unequal diameters, pawl l,standard S', pivoted lever L, and link 2,', as herein described, for thepurpose specified.

ALFRED GOODRICI'I.
